Nothing is written in case type annotations are stripped, or when validation is not requested. This process would lead to element nodes receiving the type annotation xs:untyped. This type itself is not clearly defined as "complex content" type in XDM 3.1 since it doesn't have a defintion (though this can be inferred from its intended role). I don't think there's an error per se, but I propose we clarify this most common case, for instance with a Note, proposal: <proposal> Note: when nodes have not been validated, have been stripped from their type annotations or have been created from an InfoSet, the type annotation of element nodes is xs:untyped [reference to relevant section in XP31?]. For the purpose of this section, xs:untyped should be treated as a complex type with mixed content. </proposal>
